Figure 1-9. Bridged LAN With Two Host Group Members
1.8.4 IP Routing Over Source Routing
Token Ring networks are often connected by source-routing
bridges. End-stations that communicate across a source-routing
bridging domain must be able to build routes from themselves to
their destinations, specifying the Token Rings to be traversed.
